Our year begins with the appearance of Sri Caitanya Mahaprabhu. Before He appears a number of His associates also appear, such as Advaita Acarya and Nityananda Prabhu. When Bhagavan comes He comes with a big entourage, not alone, as we find so many bogus incarnations coming alone. The knowledge of our eternal relationship with Krsna, our servitude to Him is already there in a natural state.
Mahaprabhu is not an incarnation, He is Krsna Himself. The difference is that He is tinged with magnaminity or audarya whereas Vrndavana Krsna is not. Lord Nityananda is the most merciful and Lord Caitanya is the most generous through His distribution of the Holy Name of Krsna. Anyone can join the sankirtan movement of Lord Caitanya, but it is not as generous in Krsna lila.
Through our faith, sraddha, we get close to our guardians, not by knowledge. And the most important faith is faith in the words of guru. We are not of the group that tries to outdo our guru, to do one better than our guru.
Sraddha and saranagati (surrender) are all that are required to make advancement in Krsna consciousness. Our Srila Prabhupada was empowered by Lord Nityananda to perform activities beyond human capacity.
